Infinite Sequences, Series Convergence and the Discrete Time Fourier Transform over Finite Fields

Autor: de Souza, R. M. Campello, de Souza, M. M. Campello, de Oliveira, H. M., Vasconcelos, M. M.

Digital Transforms have important applications on subjects such as channel coding, cryptography and digital signal processing. In this paper, two Fourier Transforms are considered, the discrete time Fourier transform (DTFT) and the finite field Fouri

The Discrete Cosine Transform over Prime Finite Fields

Autor: de Souza, M. M. Campello, de Oliveira, H. M., de Souza, R. M. Campello, Vasconcelos, M. M.

This paper examines finite field trigonometry as a tool to construct trigonometric digital transforms. In particular, by using properties of the k-cosine function over GF(p), the Finite Field Discrete Cosine Transform (FFDCT) is introduced. The FFDCT

Superlattice of resonators on monolayer graphene created by intercalated gold nanoclusters

Autor: Cranney, M., Vonau, F., Pillai, P. B., Denys, E., Aubel, D., De Souza, M. M., Bena, C., Simon, L.

Here we report on a "new" type of ordering which allows to modify the electronic structure of a graphene monolayer (ML). We have intercalated small gold clusters between the top monolayer graphene and the buffer layer of epitaxial graphene. We show t
